BALL-BEARING.

Specification of Letters Patent. Pattmlibed July 27, 11915.,

Application filed March 2 5, 1914. Serial No.. 827,132.

Be it known that I, CLARENCE a citizen of the United States', residing in Philadelphia, Pennsylvania, have invented lthe sleevev fir certain Improvements in Ball-Bearings, of

which the following is a spefilication.`

One object of my invention is to construct a. 'ball bearing which can be applied to a shaft at any point desired without removing any of the elements carried bythe shaft.

This object I attain by making the parts of the ball bearing in halves so that, when assembled they willA readily supportA thel shaft.

A further object of the invention is to construct the bearing so that the race for the balls will be. relievedl of pressure at the points where the splits occur.

. In the accompanying drawings-Figure 1, is a sectional'plan viewof my improved ball bearing, the 'shaftbeing in full lines; Fig. 2, is a ltransverse .sectional view on the line a--aaFig-V.- 1; Fig. 3, isla transverse sectional view on the line b-b, Figi 1; Fig. 4, v, is an endvview; vand Fig. 5,- is a perspective,

view of one Vsection of vone ofthe outer raceways. v 'y l .f

lReferring-to the drawings, is the shaft on which is mounted a two-,part :sleeve 2 and.

looselymounted on this sleeve is a flangeB. This lflange has a beveled undercut portion 4 at each'side and bearing 'against this undercut portion are the segmental vinner bearing rings 5 which are beveled at each side to conform to the bevel 4 of the central-flange and the bevel 6 of the two-part nuts 7 rwhich are screwed onto the threaded portions of the sleeve, as shown, so as to conne the bearing rings in theeproper position.` 'Ihe nuts 7 and the flange 3 are madev as shown"in Fig.

3,-having undercut grooves at each'end ofl each section, and the projection on "one vsection extends into the groove of the other section and locks the two sections irmly'together, -so that when the nuts are in.' position they are practically one unit, and, las the nuts are screwed onto the sleeve, they`. draw ing rings. "Ihese bearing vrings may be mul- E. RoBsoN,

the casing 9,

y onto the shaft and' the` tiplied if desired without departing from the mam features of the invention. 8, 8 are theouter bearing rings, each made 1n -two sections'and fitting the casing 9, which is alse made in two sections. Thetwo sections of the casing are secured together, 1n the present instance bytransverse bolts 10or'o'ther suitable fastenings. c

11, 11 are heads which are screwed into The ends 1'2 of thesev heads bear against the outer bearing rings 8 and holdthem in .proper alinement with thelinner bearing rings 5. The heads have openings considerably larger than `the shaft and l they also. have 'annular grooves 13 for the reception oflpacking 14, soas to prevent dust or `dirt gaining access to the interior ofthe bearing, and'these packing rings also 'hold the lubricant'inthe casing.

15, k15 are twoseries o balls' located bert I tween the inner and outer bearing rings, and

each' rin'g isjgrooved to form a `race-way for the balls.

In order to prevent the balls from Wea-imgthe ringsl at the corners, where onesection 1s locatedclose to another sect1on, I form transverse slots 16 and 17, one at each s ide e' near each end of the outer bearing rings 8,

as `clearly illustrated' in Fig. 5. I also4 form slots 16 and 17.n ine-the inner bearing ring,

vone at eachV side near each end of Athevsections, as clearly shown' inFigs`..2 and l5.

These slots are of a depth to allow the metal` fr om which vthegrings are made to yield shghtly'" :onder to relieve the corners of of theballs.

In 'order tofprevent-the inner bearingirings 5 from turningmonthe sleeve, I provide pins 19, which project from the sleeve 2 and -into the space betweenthe'- sections ofthe bear- -A ing, and, in order topievent the outer bearing rings Sfrom turning"independentlyrof .the outer-casing l), Iprovide pins 2 0 for the same purpose.

It willlbe-notice'd that, in order to allow the ends of the-'outer bearing rings to yield, the outer casing is cnt away, as at 21, and the sleeve is cut away, as at `22, to allow the .ends of the inner bearing Vrings `to-yield.

Screws 23 may be used, if-idesired,.to pie;

vent the heads 11 from turning inthe casing 9, or other means of fastening'may be iem-v` ployed. The exterior of the casing AIl() formed 'in'. anysuitaole mannerv to accommo ..datejianygipartieular style of` hanger; `the l.oonst' typefy hanger or support Whiehit is desirefdftusey the-above description itwill be seen am' enabled to make a' bearing which f can .be appliedlto aline shaft at -any point` desiredyfgasxeach element of the bearing is made, "inthe` present instance, in two sections and'f-theselsections are so a'ssembledfthat the with lthe:parting line .of the otherl element. Bymalging the inner and the outer bearing bearing rings at 'the ends of the segments 'I have 4vshown the two sets of balls ar- 1 desired.

5I elaim:-'- i I 1L' The combination 1n a ball bearing for a shaft, of lal two-part sleevearranged to be ,"Inountedion the shaft, said sleeve being of fan evenfdiameter throughout; 4 a two-part tcanbeadjusted longitudinally thereon; a

two-part undercut-nut mounted` on each endof" the sleeve;j:a` two-part Ainner bearing series of balls located between the two rings i of the flangeandnut and oonined'in posi- Ktion by one ofsaid'nuts; two two-part outer ,bearingringa oneouter bearingringbeing in line with one inner bearing ring and'the other outer bearing ring being in line with the other innerbearing ring 'a two-part Casing; and a" series of balls mounted between each set of innerand 'outer bearing rings.r

parting ."l'in'e of one element is .out of 'line rings in the manner shown, I prevent 'the' v'rapid-.wearing awayvof the segments of the y '..funder-cut flange loose on the sleeve so that I .'Inounted at each side of theA flange and' vshaped to. conform `to the undercut portions i and a two-part easing retaining the outer *bearing ring, the ends of each section of each nf depending upon the special v bearing ring being grooved transversely to form .yielding end sections to relieve the .balls as they pass over the joints between the' sections of the rings.

3. Thev combination of a shaft; a two-part sleeve mounted thereon; a two-part undercut-flange on the sleeve; a nut mounted on each endof the-sleeve and having a plurality 'of parts; two inner rings, each made Vof a plurality of parts, one ring being mounted between the central'llange and one nut, and the other ring being mounted between the central flange and the other nut; means for preventing the rings vturning on the sleeve;

,two outer rings having a plurality of parts,

said outer rings being in -line with the inner 'rings; a casing .inclosing the outer rings,

said casing being made in two parts; means foi-preventing the rings turning in the eas- 'l ing; two'series of balls, one series being mounted between, one set voi rings and the other series of balls being mounted between the other series of rings casing, the outer bearing rings being so'eonstructed as to allow the outer rings to accommodate themselves to the balls. i

4.*A ring forming a race-way for a ball bearing made in a plurality of parts, each section of the ringbeing weakened at a point slightlyy back of its end so that the end of the ring will .yield to relieve it from pressure. f

5. A bearing ring forming a -race-way for aball bearing 'made in a plurality of parts, each part being grooved transversely both inside and outside near the. end so asr to allow the end tofyieldslightlyto relieve the4V ringv from pressure' at the joints.
